--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> ---
Indeed.
#include <utility>
void foo (void *a, void *b)
{
std::swap (a, b);
}
> ~/install/gcc-12/usr/local/bin/g++ t.C -S -std=gnu++03
t.C: In function 'void foo(void*, void*)':
t.C:5:8: error: 'swap' is not a member of 'std'
5 | std::swap (a, b);
| ^~~~
works with GCC 11. <algorithm> is required pre C++11 for std::swap. We
have
#ifdef __cplusplus
#if defined (INCLUDE_ALGORITHM) || !defined (HAVE_SWAP_IN_UTILITY)
# include <algorithm>
#endif
but config.h was likely generated with the default C++ standard and not with
explicit -std=gnu++98.
